CHARLES H. EMERY AND JAMES P. EMERY, OF HYDE PARK, ASSIGNORS OFONE-THIRD TO DWV'IGIIT B. CARAIIICHAEL, OF LAKE, ILLINOIS.

GRAlN-CAR-DOOR FASTENER.

SPECIFICATION forming part of Letters Patent No. ll 5,668, datedNovember 19, 1889.

Application filed February 19, 1889. $erial No. 300,424- (No model.)

To aZZ whom it may concern.-

lie it known that we, CHARLES H. EMERY and JAMES P. EMERY, citizens ofthe United States, residing at Hyde Park, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inGrain-Car-Door Fasteners, of which the following is a full and completedescription.

The purpose of our invention is to securea grain-car-door fastener whichwill hold firmly in closed position a grain-car door in such manner thatthe said door cannot and will not jar out of proper place when the caris in motion,whether said car be loaded or empty,and we seek also toobtain a grain-car-door fastener which will automatically lock or fastenwhen the door is dropped or slid into a closed position.

we have illustrated our invention by the drawings accompanying thisspecification and forming a part hereof, in which Figure 1 is asectionalview showing one side of a car and a portion of the floor and roofthereof, with a grain-car door, as shown by the full lines, in a closedposition and there locked by our new grain-car-door fastener.

Our grain-car-door fastener is formed almost entirely of three pieces,and these pieces are illustrated in perspective in Figs. 2, 3, and 4 ofthe drawings.

Like letters refer to like the several views.

X is the frame of the car.

A is a car-door post or jainb.

A is a rabbet in door-jamb A, in which a grain-car door, as B, mayfreely slide vertically.

E F G are the respective parts forming our grain-car-door fastener.

It is evident on inspection thereof and by the herein-containeddescription that our improved fastener is intended for and may be usedupon any sliding door moving vertically in guides; but as the use wehave so far made of our device has consisted in looking therewith andsecuring in a closed position thereby grain-car doors, whereby grain maybeloaded and transported in bulk in cars, we have ontitled and shallhereinafter refer to our invention as a grain-car-door fastener, not,howparts throughout ever, thereby limiting its use to grain-car doors orin connection therewith.

E is a gravitydever, pivoted at c on jamb A and turning freely on saidpivot.

F is a lug or projection, termed by us a finger, having a suitable basethereon and secured firmly to jamb A.

G is a hollow projection, termed by us a thimble, integral with its base9, whereby it is secured rigidly to vertically-sliding door B.

Gravity lever E has one end thereof 6 weighted, and the other endthereof 6" is adapted to come in oontact,or nearly so,with the surface 9of thimble G. Weighted end 6 tends to hold lever E in the positionillustrated in Fig. 1 over thimble G when the door B is closed, and saiddoor cannot therefore be raised from such closed position. WVhile thedoor is raised such weighted end (2 of the lever tends to hold saidlever in such position that as the door is closed the end 6" thereof isturned to one side by the descending door, and when the door iscompletely shut the end 6" will automatically turn back into theposition over thimble G illustrated in Fig. 1. Sufficient bevel is ormay be given to side or surface f of finger F, witha like bevel "on theinner surface of thimble G coming in contact therewith, so that as thedoor B is slid downward into a closed position it is drawn forward intoclose contact at its upper end with door-jztmb A by thim ble G comingover finger F, as described.

The jarring of the car incident to the movement thereof cannot loosenthe door either by the door rising or drawing back from close contactwith the jamb because of gravity-lever E being in the position in Fig. 1over thinlble Gr, and the door is thus held rigidly in position. W'henitis desired to raise said door B, gravity-lever E is turned upon pivot6 until handle 6 thereof presses against the door or against plate g.The free end 6" of lever E will then be off from thimble G and the doormay be raised. As the dooris thus slid upward, thimble G will come incontact with weighted end 6 of lever E, and the lever will drop or turninto the position hereinbefore described, whereby when said door isagain slid downward into place said lever E Will assume the position, ornearly so, illustrated in Fig. 1, and the door will thereby beautomatically locked and securely fastened.

Having thus described our invention and its method of operation, What Weclaim, and desire to secure by Letters Patent of the United States, is

1. A device for securing vertically-sliding doors in a closed position,comprising a finger or lug secured to the door-jainb, a thinible securedto the door and adapted to cover the finger on the door-jarnb, and alever adapted to come in contact at one end thereof with the upper faceor surface of the thilnble, or nearly so, whereby the thimble is held inposition on the finger and the door thereby locked, substantiallyrasdescribed.
